I will try to address all of your concerns separately and will be happy to answer your follow up questions.
Will the antibiotic help with remove the fluid?
Yes if the diagnosis of your doctor is fluid in the ear then yes antibiotic will help but there are other drugs which are required to drain the fluid. As you must be knowing that this fluid gets accumulated because of the the Eustachian tube dysfunction (its a tube behind the nose), the drugs like systemic decongestants and local decongestants help. Local decongestants include Xylometazoline nasal spray and systemic decongestant include tab sudafed
. Xylometazoline nasal spray is required in the dosage of two puffs thrice daily for seven days and sudafed one tablet twice daily. Steam inhalation with menthol drops twice daily is also very helpful. nasal spray and sudafed can only be used if no high blood pressure issues are there. Pain killers are required to address the pain.
Is there anything else I can take OTC to help reduce the fluid?
yes all of above are OTC but one should always inform doctor before using them.
Why does it hurt below my ear?
It hurts below the ear because the infection might have spread to lymph gland below the ear.
I wish you good luck that you get well soon.
If you have any question, please let me know.
